Differences between cortical reaction and acrosomal reaction.


CORTICAL REACTION:
  • This reaction takes place within the egg.
  • In this reaction the secretory vesicles are cortical granules.
  • It prevents polyspermy by establishing a permanent barrier to additional sperm entry.
ACROSOMAL REACTION:
  • This reaction takes place within the sperms.
  • In this reaction, the secretory vesicles is an acrosome.
  • This reaction allows the sperm by exocytotic release of acrosomal enzymes to penetrate the zona pellucida of the egg.
